Hydrogen chloride

Luminol is used to reveal traces of blood in crime scenes, using a light producing chemical reaction, between many chemicals, and hemoglobin. It is a powdery compound made up of carbon, hydrogen, nitrogen, and oxygen. Mixing C8H7N3O2 (luminol) with H2O2 (hydrogen peroxide), causes it to become a liquid. Hydrogen peroxide and luminol are the two main parts of this chemical reaction. To produce a strong glow, a catalyst needs to be present. A catalyst is a substance that increases the rate of a…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

In this experiment, the competing enantioselective conversion (CEC) method was used to react an unknown secondary alcohol, which is either the R- or the S- enantiomer, with S-HBTM and R-HBTM separately. Thin-layer chromatography (TLC) was used to determine which reaction was faster. If the S-HBTM was faster, then the unknown secondary alcohol had the R configuration. If the R-HBTM was faster, then the unknown secondary alcohol had the S configuration. 1H NMR was used to determine the molecular…

was faster than Chloride, because on the periodic table, Iodine has a bigger atomic size, while Chlorine has the higher electronegativity, but size trumps electronegativity, as according to ARIO rules. This means that Iodine is more acidic than Chlorine, which means that in the reaction, the Iodide could displace the Bromine from the 1-bromooctane, because it has a bigger size, much faster than the Chloride, thus attesting the notion that Iodide is the more reactive than Chloride in the reaction…

The element I selected for the Element Research Project is Osmium. Osmium’s chemical symbol is Os. Osmium’s atomic mass is 190 amu. Osmium’s atomic number is 76, it has 76 protons and 76 electrons. Osmium also has 114 neutrons. Osmium belongs to the transition metal group in the middle of the periodic table. Osmium’s Bohr model with electric configuration has two electrons in the first shell, eight in the second shell, eighteen is the third shell, thirty two in the fourth shell, fourteen in the…

demonstrates how the results of two reactions can create a colored flame with the sugar in the gummy bear. When potassium chlorate is heated to its molten state, it goes through a thermal decomposition reaction that causes it to dissociate into potassium chloride and excess oxygen. The gummy bear is mostly made up of sugar and causes a combustion reaction when mixed with the excess oxygen. Carbon dioxide and gaseous water are released as a result of the reaction. The purple flames that arise are…

In this experiment I will prepare a pure sample of an element (copper) by making a copper solution and then plating it out onto a more active metal. HYPOTHESIS: Because Copper is a more active metal than Iron, I believe the copper solution will plate onto the iron nail. PURPOSE: The purpose of this experiment is to observe reactions between metals depending on which one is more active and observe how to clean pennies, while making a copper solution. RAW MATERIALS: Two plastic cups Clover…

3.2 Mechanochemical synthesis The mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP 27…
